  2. Arrhenius equation - Wikipedia

    en.wikipedia.org/wiki/Arrhenius_equation

    This has the same form as an equation for a straight line: = +, where x is the reciprocal of T. So, when a reaction has a rate constant that obeys the Arrhenius equation, a plot of ln k versus T −1 gives a straight line, whose gradient and intercept can be used to determine E a and A .

  3. De Bruijn graph - Wikipedia

    en.wikipedia.org/wiki/De_Bruijn_graph

    If n = 1, then the condition for any two vertices forming an edge holds vacuously, and hence all the vertices are connected, forming a total of m 2 edges. Each vertex has exactly m incoming and m outgoing edges. Each n-dimensional De Bruijn graph is the line digraph of the (n – 1)-dimensional De Bruijn graph with the same set of symbols. [4]

  4. Image histogram - Wikipedia

    en.wikipedia.org/wiki/Image_histogram

    An image histogram is a type of histogram that acts as a graphical representation of the tonal distribution in a digital image. [ 1] It plots the number of pixels for each tonal value. By looking at the histogram for a specific image a viewer will be able to judge the entire tonal distribution at a glance. Image histograms are present on many ...

  5. Arrhenius plot - Wikipedia

    en.wikipedia.org/wiki/Arrhenius_plot

    Arrhenius plot. In chemical kinetics, an Arrhenius plot displays the logarithm of a reaction rate constant, ( , ordinate axis) plotted against reciprocal of the temperature ( , abscissa ). [ 1] Arrhenius plots are often used to analyze the effect of temperature on the rates of chemical reactions. For a single rate-limited thermally activated ...

  6. Archimedean spiral - Wikipedia

    en.wikipedia.org/wiki/Archimedean_spiral

    Taking the mirror image of this arm across the y-axis will yield the other arm. For large θ a point moves with well-approximated uniform acceleration along the Archimedean spiral while the spiral corresponds to the locations over time of a point moving away from a fixed point with a constant speed along a line which rotates with constant ...

  7. Zazzle - Wikipedia

    en.wikipedia.org/wiki/Zazzle

    C#/ASP.NET. [ 1] Zazzle is an American online marketplace that allows designers and customers to create their own products with independent manufacturers (clothing, posters, etc.), as well as use images from participating companies. Zazzle has partnered with many brands to amass a collection of digital images from companies like Disney, Warner ...

  8. Linear equation - Wikipedia

    en.wikipedia.org/wiki/Linear_equation

    The phrase "linear equation" takes its origin in this correspondence between lines and equations: a linear equation in two variables is an equation whose solutions form a line. If b ≠ 0, the line is the graph of the function of x that has been defined in the preceding section. If b = 0, the line is a vertical line (that is a line parallel to ...
